Abstract：
OBJECTIVE: Vitreomacular traction (VMT) has unique presentations in eyes with diabetic retinopathy (DR). This study aimed to investigate the characteristics and clinical course of VMT in DR.
METHODS: A retrospective case series.
METHODS: Thirty eyes from 30 patients with DR and concurrent VMT were retrospectively enrolled. Baseline and final best-corrected visual acuity (BCVA) and optical coherence tomography (OCT) characteristics were reported. Linear regression models were used to analyze the correlating factors for visual outcome.
RESULTS: Of the 30 eyes, a thickened posterior hyaloid membrane was noted in all cases and multi-layered traction from different directions in 14 eyes (46.7%). Twenty-one eyes (70%) had tractional macular retinoschisis, seven (23.3%) had foveal detachment, five (16.7%) had a lamellar macular hole, and three (10%) had a full-thickness macular hole, including two with macular hole retinal detachment. Three eyes had spontaneous release of the VMT within 3 months of observation. For the remaining 27 eyes receiving operations, the VMT, full-thickness macular hole, and serous foveal detachment all resolved postoperatively with residual macular schisis in 6 eyes (22.2%) only. None of the baseline OCT characteristics were associated with postoperative BCVA (P > .05).
CONCLUSIONS: VMT in DR had a thickened posterior hyaloid, and many of them had multi-layered traction and/or concurrent macular retinoschisis. Lamellar macular hole, full-thickness macular hole, or concurrent retinal detachment may also occur. Spontaneous resolution of VMT rarely occurred, and those who underwent operation for VMT had improved vision and macular structures with resolution of the macular hole and retinal detachment.

摘要：
目的：玻璃体牵引（VMT）在糖尿病性视网膜病变（DR）的眼中具有独特的表现。本研究旨在探讨DR中VMT的特点和临床过程。
方法：回顾性病例系列。
方法：对30例DR并发VMT患者的30只眼进行回顾性研究。报告了基线和最终最佳矫正视力（BCVA）和光学相干断层扫描（OCT）特征。线性回归模型用于分析视觉结果的相关因素。
结果：在30只眼睛中，在所有情况下都注意到后透明膜增厚，并且在14只眼中从不同方向进行了多层牵引（46.7％）。21只眼睛（70％）有牵引性黄斑视网膜劈裂，7人（23.3%）有中央凹脱离，5人（16.7%）有层状黄斑裂孔，三个（10%）有一个全厚度黄斑孔，包括两个黄斑裂孔视网膜脱离.三只眼睛在观察的3个月内自发释放VMT。对于其余27只眼睛的接收操作，VMT,全厚度黄斑裂孔，浆液性中央凹脱离均在术后缓解，仅6眼(22.2%)黄斑裂片残留。无基线OCT特征与术后BCVA相关(P>.05)。
结论：DR中的VMT具有增厚的后透明样，其中许多患者有多层牵引和/或并发黄斑视网膜裂孔。板层黄斑裂孔，全厚度黄斑裂孔，或并发视网膜脱离也可能发生。很少发生VMT的自发消退，接受VMT手术的患者视力和黄斑结构改善，黄斑裂孔和视网膜脱离消退。
